APPARATUS FOR USE IN CLEANING BEE R-COILS- Specification of LettersPatent.

Patented Aug. 21, 1906.

To all whom it may concern.-

Be it known that I, CHARLES ALoNZo CHANDLER, a citizen of the UnitedStates, residing at Carlisle, in the county of Cumberland and State ofPennsylvania, have in vented an Improved Apparatus for Use in CleaningBeer-Coils, of which the following is a specification.

The coils through which lager-beer and other malt liquors are drawn atbars require to be cleansed from time to time, and this is accomplishedwith difficulty and imperfectly by the old and usual method, whichinvolves the use of a funnel at the bar and a bucket or other receptaclein the cellar or lower apart ment. Aplparatus has also been devised bywhich a so ution of some caustic or alkaline material may be forcedthrough a pipe-coil and followed by a stream of pure water for washingout any portion of the chemical substance which may adhere to the pipe.I have devised an improvement in this line which is distinguished bysimplicity and cheapness of construction, ease of detachability of itscomponent parts, and effectiveness in operation.

The details of construction, arrangement, and operation of the apparatusare as hereinafter set forth, and illustrated in the accompanyingdrawings, in which- Figure 1 is a perspective view of the apparatus, andFig. 2 a longitudinal section of the receptacle for the causticmaterial. The said receptacle is indicated by 1, and consists of acylinder having detachable heads and a top screw plug 2, to the soda orlye. Apipe 3 is screwed into one end of the cylinder, and a pipe 4 issimilarly connected with the opposite end and extended vertically, asindicated at 4*, such extension being adapted for attachment to abeercoil. (Not shown.) Both the front or induction pipe 3 and the rearor eduetion pipe 4 are provided with stop-cocks 5, as shown. The frontend of pipe 3 is adapted for attachment to a hot-water pipe. (Notshown.) Parallel with the cylinder 1 and its pipes 3 4 is ar; rangedanother pipe, 6, which is provided with stop-cock 7 and connected at thepoint 8 with the eduetion-pipe 4. The front end of the pipe 6 isadaptedfor attachment to a coldwater pipe. (Not shown.) It will be seenthat the induction and eduetion pipes 3 and 4 provide for filling thecylinder with are connected with the opposite ends of the alkaline-tank1, so that water pumped to the latter by pipe 3 passes directly throughinto pipe 4, this being the simplest arrangement and enabling thealkaline-tank to be made smaller than would be otherwise practicable andalso that all the parts of the apparatus are easily detachable from eachother, so that space may be econo'inized in packing for storage ortransportation.

In using the apparatus the beer-coil having been detached from the kegfrom which the beer has been drawn it is connected with the verticalextension 4 at the point 9. Then the stop-cock of pi e 6 being heldclosed, as indicated by full lines, the stopcooks 5 of the other pipes 34 are opened that is to say, drawn into the position indicated by dottedlines-and hot water is thus allowed to flow into and through thecylinder 1, whereby the caustic substance is dissolved to a greater orless extent and the hot solution carried onward through the pipes 4 4and into and through the beer-coil, it being finally discharged into thebeer-trough or other recepacle at the draw-faucet in the barroom. Afterthe coil has been thus duly treated with the caustic solution thestopcocks 5 are closed, and the cock 7 of pipe 6 is opened to permitcold water to flow through said pipe and the vertical extension 4 of thehot-water pipe, and thus through the beer-coil for the purpose offlushing the latter or thoroughly washing out the caustic solution andany foreign matter which may have been combined with or loosened by thesolution.

It will be understood that the hot and cold water pipes, connected,respectively, with the pipes 3 and 6 of the apparatus proper, may beconnected with the ordinary service-pipes.

What I claim is The improved apparatus for cleaning beerpipe coilsconsisting of a cylinder for holding a caustic substance, alined inletand outlet hotwater pipes 3 and 4, connected with the opposite ends ofthe cylinder and each provided with a stop-cock, and a supplementalcoldwater pipe provided with a stop-cock and connected with theoutletpipe at point in rear of its stop-cock, as shown and described.
